State departments of transportation began using recycled concrete aggregate (RCA) as aggregate in portland cement concrete pavement in the United States in the late 1970s. Although RCA is rarely used in current rigid pavement slabs, the impetus for its continued use remains the same: a lack of landfill space, a shortage of nearby quality natural aggregates, or both.

Our Flex Base material is frequently used to weather proof a project, such as a cap on building pads or for building staging areas, which reduces lost time from rain delays. Crushed concrete conforms to the Flex Base specification of the Texas Department of Transportation. Download TxDOT Product Specifications

In Texas, rigid (or portland cement concrete) pavements and flexible (or asphaltic concrete) pavements are most often constructed using crushed limestone and/or siliceous river gravel as the coarse aggregate. Project 1244, sponsored by the Texas Department of Transportation .

Crushed Concrete for Driveways Patios . When old structures made of concrete are renovated or demolished, the companies specializing in the field of concrete recycling collect this material from demolition sites and put it through a crushing plant to create a new end product: crushed concrete or recycled concrete aggregate (RCA).

Mar 14, 2018· Abstract. The primary objectives of this project included the collection of information on continuously reinforced concrete pavement (CRCP) behavior and performance in Texas to calibrate the mechanisticempirical pavement design procedure for CRCP developed under TxDOT research study 05832, and the overall evaluation of rigid pavement performance in Texas, including special and .

Concrete Sand. Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate.

Spalling is a very common distress type in siliceous river gravel (SRG) continuously reinforced concrete (CRC) pavements along transverse cracks. It refers to the dislodging of concrete segments (>½" in depth) along a joint or crack in a concrete slab within m (2 ft) of a joint or crack (SHRP 1993).

Case studies on the use of recycled aggregate concrete in road pavement construction ... In 1995, the Texas Department of Transportation began reconstruction in Houston in a section of IH10 ( km) with continuously reinforced concrete pavement (CRCP) made with coarse and fine RCA. Demolished concrete from the existing pavement was used.
