What is Hot Mix Asphalt Pavement? - apa-mi.orgAsphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. Asphalt cement is heated aggregate, combined, and mixed with the aggregate at an HMA facility. The resulting Hot Mix Asphalt is loaded into trucks for transport to the paving site.
VDOT Mixes & Guidelines - vaasphalt.orgVDOT "Standard" Base Mix. As the name implies, the base mix is the base asphalt layer for the pavement structure. Its major function is to provide the principal support of the pavement structure. The base mix uses the largest aggregate particles to provide resistance to rutting and to bottom-up fatigue cracking.
Mississippi Asphalt Pavement AssociationAsphalt Fact #9 Smoother pavements extend pavement life by as much as 10% to 25%. Asphalt Fact #63 Asphalt is 100% renewable, but reclaimed concrete is just porous rock. Asphalt Fact #113 Often it is possible to route runoff from roofs and roads into the stone recharge bed of a porous parking lot.

Understanding the differences between hot mix asphalt and ...Asphalt pavement is a mix of coarse aggregate stone, sand, fine aggregate and asphalt cement, which is petroleum based. Depending on the asphalt manufacturing process and temperatures used, it is either considered hot mix asphalt or warm mix asphalt.
Road surface - WikipediaA road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course .
The Complete 7-Step Process for Asphalt Pavement InstallationIt is very rare to install an asphalt surface that does not connect to existing driveways, roadways or parking lots. As such, asphalt-paving contractors must find a way to smooth the transition from old surface to new. Butt joints are areas were old asphalt or concrete meets new asphalt pavement.
