Asphalt Group

The Asphalt Group at the Materials Control, Soils, and Testing Division is committed to ensuring that only quality asphalt products are used in constructing and maintaining our highways for the citizens of West Virginia.  We will be proactive in maintaining and developing education, testing, inspection, and quality assurance programs that use the latest processes and technology that meet State and Federal specifications.  

Tests that we perform                                                                             

AMRL Certified to Test:

The Asphalt Laboratory participates in the AASHTO Materials Reference Laboratory (AMRL) Asphalt Testing Proficiency Sample Program.  


The Asphalt Group also assists in the technician certification programs, hosts educational workshops, and provides training for district laboratory staff.  We assist in the implementation of new specifications, special provisions, and design directives that concern asphalt within the State’s highway system.  The Asphalt Group staff supports the Pavement Group within the MCS&T by conducting pavement surveys, evaluating asphalt cores, and assisting in education and training seminars. 

Standard Specifications Roads and Bridges

The West Virginia Division of Highway’s Standard Specifications Roads and Bridges governs the materials that are used on West Virginia’s highways.  It is important that the Asphalt Group understands these specification, how they affect construction of our roadways, and how they affect the lifespan of asphalt roadways in the State.  The sections of this specification that cover asphalt and asphalt materials are listed below: 

Division 400: Bituminous Pavements

Section 401: Asphalt Base, Wearing, and Patching and Leveling Courses
Section 402: Asphalt Skid Resistant Pavement
Section 405: Surface Treatments
Section 408: Tack Coat
Section 410: Asphalt Base and Wearing Courses, Percent within Limits (PWL)
Section 412: Winter Grade Asphalt Patching Mixture
Section 415: Milling ofAsphalt Pavement Surface

Division 700: Materials Details

Section 705: Asphalt Materials

Material Procedures                                                                                                          

It is important to perform all procedures associated with sampling, testing, reporting, and inspection appropriately in order to maintain a reliable quality assurance system. This is accomplished by use of Division approved Materials Procedures (MPs). These MPs are numbers to coincide with the Standard Specifications, as such The Asphalt Maintains the 400 Series of MPs.  The following is an individual list of MPs currently maintained by the Asphalt Group:
