Cement-Treated Base Cement-treated base (CTB) is a mix of native soils and/or manufactured aggregates with measured amounts of portland or blended cement and water, which hardens after compaction and curing. CTB Applications: CTB forms a …

Abstract: Cement-treated base (CTB) is a mixed-in-place or central-plant-produced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.

Durability of the road base subjected to wetting/drying and freezing/thawing cycles is a critical parameter for any road -way’s satisfactory performance. The durability issues are especially challenging in wet, northern climates where deeply penetrating freeze-thaw patterns can cause the unstabilized pavement base to lose strength and stiffness.

This document provides a basic guide on the use of cement-treated base (CTB) for pavement applications. It provides an overview on the design and construction of CTB for both mixed-in-place and central plant mixed operations.

Cement-treated base (CTB) - refers to all hardened soil-cement that meets the project specifi ed minimum durability and strength requirements for a base. CTB uses more cement than CMS, resulting in a strong, durable, frost resistant layer for the pavement structure.

A Historg of Superior Performance for Heavg-Dutg Pavements Roller-Compacted Concrete (RCC) consists of an engineered mixture of dense-graded aggregates, cement and water. This zero-slump concrete mixture, when placed with an asphalt paver and compacted to high density, provides a high-strength, durable pavement structure. RCC uses no forms, requires no conventional finishing, and needs no ...
