What is the density of asphalt paving? Quora
Answer (1 of 3): 2400kg per cubic metre is a good generic density Sorry if you use the imperical system, I'm sure you can convert it easy enough In real life though, it's a good idea to calibrate this figure based on tonnage used, average depth and coverage, especially if you are recieving mateHere, the Standard test method for determining the bulk density of concrete is given in ASTM C138 / C138M (AASHTO T 121M/T 121)  Standard Values of Concrete Density We have found the following sources where the standard value of the density of concrete is provided The density of normal concrete is 2400 kg/m 3 (150 pcf or lb/ft 3) and the density of lightweight concrete is 1750Density (Unit weight) of Concrete Bulk Density Civil· Standard asphalt density is 145lbs/ft3 or 2322kg/m3 The asphalt unit weight is 2243 per cubic meter Therefore 24 ton of asphalt = 1 cubic meter 1 cubic yard of hot asphalt mix weighs 2025 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 forHow Many Tons Are In A Square Yard Of Asphalt 2020
Density of Construction Materials in kg/m3 and lb/ft3
Density Values of Different Construction Materials If two different materials are same in weight, but their density of both may be different Lower dense material occupies more volume than higher dense material Density also decides the sinking property of material It is decided by knowing the density of liquid If the material has lower density than liquid, then it will float on the surfaceAsphalt concrete base (ACB), also called asphalt treated base (ATB), is a densegraded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1) In addition to site paving benefits, ACB can be advantageous because it can provide: A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure IfAsphalt Concrete Base (ACB) – Pavement InteractiveTo design the Asphalt concrete mix using Marshall method 113 MARSHALL METHOD OF MIX DESIGN In this method, the resistance to plastic deformation of a compacted cylindrical specimen of bituminous mixture is measured when the specimen is loaded diametrically at a deformation rate 53 of 50 mm per minute There are two major features of the Marshall method of mix design (i) densityChapter 11 MARSHALL METHOD OF ASPHALTCONCRETE MIX

Asphalt Concrete an overview | ScienceDirect Topics
Asphalt concrete is often touted as being 100% reclaimable or recyclable and, as a result, very little asphalt concrete is actually sent for disposal in landfills Asphalt recycling on a large scale (inplace asphalt recycling or asphalt recycling performed at a hot mix plant) and asphalt recycling on a smaller scale are used For smallscale asphalt recycling, the user separates asphaltadequate density COLD MIX ASPHALT CONCRETE Cold mix Asphalt Concrete, or cold placed mixture, is generally a mix made with emulsified or cutback asphalt Emulsified asphalts may be anionic or cationic MS or SS grades Aggregate material may be anything from a densegraded crushed aggregate to a granular soil having a relatively high percentage of dust At the time of mixing, theChapter 2 Asphalt and Asphalt Paving Materials· As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs per cubic foot The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used Lightweight concrete has a density of 115 lbs per square footUnderstanding the Density of Concrete • Aggregate Research
