San Antonio Asphalt Paving, 24-7 Under Pressure - Asphalt Paving Service

Nov. 2, 2011 - PRLog -- Asphalt Paving
New Pavement Applications are performed with a lay down machine to ensure a proper bonding.  There are several types of asphalt one may use for specific jobs;
-   TYPE ‘A’ Hotmix -  Largest size rock, low sand mixture; Highway mix
-   TYPE ‘B’ Hotmix – Average mixture of sand and rock; great  for Roads and Lots
-   TYPE ‘C’ Hotmix – Finer rock, higher sand mixture; less common Type used under certain specs
-   TYPE ‘D’ Hotmix – Finest mix, small rock; Patching mix
-   COLD MIX – Mixture
From A to D the difference represents the size of the rock and the amount of sand in the mixture.  TYPE A is the largest rock and lowest amount of sand and TYPE D is the finest rock with highest amount of sand in the mixture.
For new pavement applications we apply the standard 2” thick asphalt.  Any new pavement is going to require a sub-surface base application.  The base will then be compacted and cure for about (24) hours before laying asphalt.
Any retaining walls, additional support or drainage concerns will be addressed during this process to ensure proper bonding that is durable and solid enough to endure years of weather stress.
The application require a (6) man crew consisting of; (3) heavy machinery operators; Lay Down Machine, Roller and Bobcat. There will also be (2) ground guys and (1) Supervisor.  Our operations are extremely well coordinated in respect to the deadline as well as providing quality work.
Once the base is appropriately compacted, the asphalt laying process is relatively quick and its curing time is only a period of (24) hours prior to traffic.
There is also another service known as Over Laying which means you can run the lay down machine over an existing surface to help restore it. This is a process which is done to save an existing fatigue cracking issue by simply over coating the top with Hotmix.  This application only requires between 1.00” – 1.50” thick asphalt.  
There is no base application required during this process, the surface will then cure within (24) hours.  This function can also be a solution to certain lot imperfections such as bird nests, edging…
The surface is then inspected by a 24-7 Under Pressure supervisor to ensure the quality of the application before each lot is released.  

Asphalt Repairs
            This service is available for all types of patches and all sizes.  We simply cut a perfect square around the patch to ensure proper bonding of the material within all areas of the patch.  The area is then dug-up with a Bobcat and a (3) man crew total including the (1) machine operator and (2) ground guys.  
For patches we typically use TYPE ‘B’ Hotmix and use 1.50” of filler to stabilize the patch. This process is relatively fast. When there is no additional base to be compacted, this usually takes (1) day to complete.
The surface is then compacted with a Roller or plate compactor depending on size.  All patches are subject to a (24) hour curing time as well.
The surface is then inspected by a 24-7 Under Pressure supervisor to ensure the quality of the application before each lot is released
