MODIFIED SUBBASE is also known as road rock, road stone, base stone, class A road stone, class A road rock, shoulder stone, surfacing stone, modified subbase, and granular subbase. Pattison produces MODIFIED SUBBASE in our state-of-the-art, jaw/cone crushing plant. Our crushing plant features compression crushing technology that limits fines generation and increase fractured faces.
Modified Subbase Quality
We understand that source quality makes a significant difference in the longevity of aggregates. Our facility in Clayton, Iowa features 9 ledges that include ordovician dolomitic limestone, limestone and sandstone. Pattison MODIFIED SUBBASE has been used in several projects conducted by Iowa State University. It has been designated as “high strength” stone and has demonstrated a longevity that exceeds most other quarry MODIFIED SUBBASE.
Pattison Modified Subbase Value
Qualitative testing has established that Pattison’s high strength MODIFIED SUBBASE saves substantial time and materials for end users. With our direct to rail transfer system, Road Rock products move quickly from production to rail cars with minimal handling. This reduces product degradation and lowers load out costs.
