Highway asphalt thickness
WebThe Pavement: Hot mix asphalt (HMA) is a high-quality mixture of asphalt cement and well-graded, high-quality aggregate that has been thoroughly compacted to ensure long-term performance. Asphalt concrete mixes are designed as either a base course or a surface course. The base course provides adequate load distribution properties. WebAsphalt Pavement. 2389 Gateway Oaks Suite# 200.
