Reclaimed Asphalt

Posted by on 25/ 11/ 15

According to the standard, the use of RAP for SMA is permissible. The types, quan­tities, and requirements for RAP to be used in SMA mixes should be specified in an NAD appropriate to the intended use.

RAP should be classified according to EN 13108-8 and should conform to the relevant requirements for a particular application.

The maximum size of a particle in RAP cannot be larger than size D of the SMA mix. The quality of aggregate in RAP cannot deviate from the requirements for a new aggregate to be used in a given SMA.

When the used RAP contains road binder (unmodified) and when the binder added to the mixture is road binder then additionally one of two values should be determined: either the penetration at 25°C or the softening point (R&B) of a mixture created by combining the recover...

Complex and Special-Care Areas

Posted by on 25/ 11/ 15

Installing wallcovering would be a snap if there were no corners, doors, windows, and electrical outlets, where you need to use extra care.

TILTING TRIM

AND COCKEYED CORNERS

In renovation, trim and corners are rarely per­fectly plumb, but strips of wallcovering must be, regardless of tilting trim and corner walls out of plumb. If your first strip begins next to an out-of-plumb jamb casing, overlap it by the amount the casing is off plumb. After brushing

Подпись: Fixing Three Small Flaws ► A paste lump under the covering. First try to flatten it with a plastic wall smoother. This may take several gentle passes. (Don't use a metal blade because it would snag on the lump and tear the wallpaper.) If there are many lumps, the paste is unevenly mixed. In this case, pull the strip off the wall, and sponge the wall clean. Then adjust or replace your paste mix, and start with a new strip. ► Air bubbles that you can't brush out. This is a common problem with vinyl wallcoverings. Use the point of a razor knife to cut a small slit. As you gently force out the air with a smoothing brush, the slit will flatten out and then become unnoticeable. ► Edge not adhering. Pull it away from the wall slightly and dab on paste with a small brush. Avoid stretching the covering, especially if it's vinyl.

out the wallpaper, trim the overlapping edge.

Thus the leading edge of that strip will be plumb, as will the next strip’s. But always double-check for plumb before hanging subsequent strips.

Z-Glass House

Posted by on 25/ 11/ 15

This contemporary design does not have a pronounced gabled roof or loft. It looks a lot like the New Popomo, but is about three times bigger. Like its smaller cousin, the Z-Glass House has a glass wall that is intended to face south during the winter for solar gain. This design includes a stain­less steel counter, sink, range and refrigerator, a full bath and a fire­place. While it is not built on inte­gral wheels, it is small enough to be moved on a trailer. It is shown at right with hot rolled steel siding. [5]

. Three Types of Seams

Posted by on 25/ 11/ 15

You can join strip edges in three ways: butt seam, overlap seam, or double-cut seams.

► The butt seam is the most common, its edges are simply butted together and rolled with a seam roller.

► An overlap seam is better where corners are out of sguare or when a butt seam might occur in a corner and not cover well. Keep the overlap as narrow as possible, thereby avoiding a noticeable welt and patterns that are grossly mismatched.

► Double-cut seams (also called through-cut seams) are the most complex of the three. They are used primarily where patterns are tough to match or surfaces are irregular; for example, where the walls of an alcove aren’t sguare.

Material Organization and Cutting

Posted by on 25/ 11/ 15

Material Organization, Mitre Saw

1. Set up your table in convenient locations for moving lumber in and out.

2. Place the incoming material as close as possible to the side of the saw where you will be positioning it to cut.

3. As it is cut, stack the lumber in a pile that is neat and easy to pick up and carry or lift with a forklift.

4. Put scrap wood that you will be cutting into stacks nearby, maybe under the saw table.

Cutting with a Mitre Saw

1. Set your length gage for multiple cuts.

2. Cut your first piece, then check the cut for square (both vertical and horizontal) and correct length.

3. Check the second and tenth piece for square and length.

4. Check every tenth piece after that for length.

5. Keep lumber tight against lumber guides, but don’t bang them so that they move.

Hydraulic energy – water mills and windmills

Posted by on 25/ 11/ 15

We have seen the first use of hydraulic energy in China under the Han Empire, at the beginning of the 1st century AD. The Chinese devices are quite complex from the very beginning, in contrast to the comparable but simpler devices developed at the same time in the Roman Empire. There, simple horizontal-axis mills are used to turn a grindstone. But in China there are complex devices powered by vertical-axis water wheels, according to all evidence. These wheels power batteries of pestles for agricul­tural or metallurgical use (21 AD). In the industrial center of Nanyang they power bat­teries of bellows to provide combustion air for the melting and casting of iron (31 AD).

It is probably in the 4th century that the direct use of rotating wheels to grind grain was developed, in response to d...

Natural Asphalts

Posted by on 25/ 11/ 15

Natural asphalt may be employed for SMA as an additive to the road binder or modi­fied binder under the following conditions:

• If it conforms to the requirements of EN 13108-4, Annex B, Tables B.1 and B.2, for natural asphalts with high or low-ash contents, respectively

• When natural asphalt is being incorporated in the road or modified binder by means of the following:

• Intermixing with heated binder in a liquid state in a tank

• Direct batching into a pugmill in the case of natural asphalt in the form of a powder or granulate with particles not exceeding 10 mm

ACOUSTICAL STANDARDS AND DESIGN

Posted by on 25/ 11/ 15

Federal Highway Administration (FHWA) regulations for mitigation of highway traffic noise in the planning and design of federally aided highways are contained in Title 23 of the United States Code of Federal Regulations, Part 772. Requirements during the planning and design of a highway project include identification of traffic noise impacts, examination of potential mitigation measures, inclusion of reasonable and feasible noise mitigation measures, and coordination with local officials. The regulations contain noise abatement criteria for different types of land uses and human activities. Reasonable and feasible efforts must be made to provide noise mitigation when the criteria are exceeded...

Install the base cabinets in kitchens and baths

Posted by on 25/ 11/ 15

Cabinet installation details are the same, whether you’re working in the kitchen, the bathroom, or any room. Some people prefer to install wall cabinets first so they won’t have to reach over the base cabinets. Perhaps because I am tall, I gen­erally install base cabinets first. Either way, it’s best to begin in a corner. Corner cabinets tend to be large and are trickier to install because

Kitchen cabinets are seen and used every day. It’s important that they be installed with care, leaving them plumb, level, and straight. [Photo by Don Charles Blom]
