Asphalt leveling course is defined as a layer of asphaltic concrete pavement of varying thickness spread on an existing pavement to compensate for irregularities prior to placing the surface or wearing course. As you may or may not know, an asphalt pavement section or structure is made up of multiple and different asphalt layers (lifts or courses).
SirAl (Geotechnical) 1 Jul 04 21:25. Depends upon the mix properties and compaction criterion. I commonly use between 2250 kg/m3 (140 lb/ft3) and 2350 kg/m3 (147 lb/ft3) for in-place density (conventional ACP mix) in my neck of the woods. Here we are dealing agg spec gravs of 2.68 for crush product and around 2.60 for natural fines.
Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.
A stronger surface course and laid a little thicker 30 - 40mm in a normal thickness; 30% 14mm Hot Rolled Asphalt. A very close textured and hard wearing surface course normally used for carriageways and industrial estates where heavier usage is anticipated. Will resist static turning from heavy vehicle and forklift trucks.
Abstract - Hot mix asphalt wearing course in a flexible road pavement is the most important and critical layer in ... concrete wearing course of flexible pavement. Laboratory tests were carried out on the aggregate, bitumen and ... particle density after compaction but adjusted slightly to make room for sufficient bitumen .
The open gradation creates pores in the mix, which are essential to the mix's proper function; therefore, anything that tends to clog these pores, such as low-speed traffic, excessive dirt on the roadway or deicing sand, should be avoided. Figure 1. Core from an pavement using an open-graded mix as the wearing course (from NAPA, 2001). Figure 2.

As asphalt concrete wearing course is the first layer in the pavement structure, the material should be able to sustain stresses caused by direct traffic loading without causing premature cracking. The fatigue resistance of bituminous mixture is its …
The weight increase using asphalt is high with approximately 250 kg per m2. When applying a wearing course the weight increase is 15-18 kg per m2. On a bridge deck of 100 m2 this is 25,000 kg for asphalting, compared with 1,500-1,800 kg in the case of a wearing course. Check our advisory tool (Dutch)

Power-sweep the surface and dispose of asphalt millings offsite. Pave with a 3/4″ leveling course to increase ruggedness, durability, and smoothness. Pave with a 1.5″ wearing course. For driveway resurfacing, 1,500 square feet is approximately $3,690. 5,000 square feet is …
The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field.It is located under the surface layer consisting of the wearing course and sometimes an extra binder course.. If there is a sub-base course, the base course is constructed directly above this layer.
Asphalt Concrete Paving, Asphalt Concrete Placement, Asphalt Wearing and Binder Course, Asphalt Concrete Compaction, Asphalt Concrete Testing Polymer modified asphalt mix shall be placed and compacted at a temperature determined from the viscosity-temperature relationship which is estimated to be in the range of 155°C to 165°C.
According to the Malaysian Public Works Department specification (JKR/SPJ/2008-S4) , porous asphalt is a special-purpose wearing course. It is produced using open-graded aggregate mixed with ...

Concrete, Asphalt weighs 2.243 gram per cubic centimeter or 2 243 kilogram per cubic meter, i.e. density of concrete, Asphalt is equal to 2 243 kg/m³. In Imperial or US customary measurement system, the density is equal to 140 pound per cubic foot [lb/ft³], or 1.297 ounce per cubic inch [oz/inch³]. More ›.
Standard asphalt density is 145lbs/ft3 or 2322kg/m3. The asphalt unit weight is 2243 per cubic meter. Therefore 2.4 ton of asphalt = 1 cubic meter. 1 cubic yard of hot asphalt mix weighs 2.025 tons or 4050 lbs. These measurements are an approximation and therefore when you are ordering the quantity ensure that you add more asphalt to gather for ...

The Asphalt Institute strongly endorses the use of RAP in asphalt mixtures. RAP has a history of positive performance. The specifying agency or owner will set the limit for RAP content. Almost all state highway departments now allow the use of RAP. A few restrict its use in wearing courses; even fewer (one or two) prohibit its use completely.
asphaltic concrete wearing, binder and base course mixtures of the plant mix type. This work consists of furnishing and constructing one or more courses of asphaltic concrete mixture applied hot in conformance with these specifications and in conformity with the lines, grades, thicknesses and typical sections shown on the plans or established.
Answer (1 of 5): I found 2243 kg/m3 for asphalt. That means we need to convert kg to tons, basically — and I know 2.205 lbs = 1 kg, which scales up to 2000 lbs = 907.0 kg, so each ton is 907.0 kg. New question: how many m3 are in 907 kg? We'd have one whole m3 if we had 2243 kg, but we only h...
