With the increasing pursuit of pavement comfort, asphalt pavements have gradually become the main structural forms of high-grade pavements . The early disease of asphalt pavements is related to the construction quality limestone rock asphalt pavementPermanent Pavement Patch - RockAsphalt©Our naturally-occurring asphalt on the other hand? Well since the Cretaceous period, heat and pressure have caused concentrated bitumen to impregnate the Anacacho limestone deposit we mine in South Texas. That means the adhesive that binds our patching material together has seeped deep inside our asphalt rocks. And that matters if you care about the longevity of a pavement patch.

Improving DMS 9210 Requirements for Limestone Rock

Limestone rock asphalt (LRA) is a relatively porous stone permeated with a very hard natural asphalt. The material is found in very large deposits in the southwest corner of Uvalde County and extending into Kinney County. LRA is quarried with the aid of explosives, which create tremendous piles of rubble, including very large boulders.ITEM 330 LIMESTONE ROCK ASPHALT PAVEMENT (Class The limestone rock asphalt aggregate shall have an average bitumen content of 5.0 to 9.0 percent by weight of naturally impregnated asphalt as determined by Test Method Tex-215-F.
