Over 3 million tons of Texas Crushed Stone’s crushed limestone has been used for railroad ballast.  Railroad ballast is typically graded from 1 ¾” or 1 ¼” to ½”.  Ballast is open graded and washed over a screen as part of the production process. Railroad Ballast supports the railroad ties.  Because ballast is a large […]

Well Graded Concrete Aggregate

Over the years, I have wondered why the ASTM specifications for concrete aggregate have a gap in the aggregate grading between the ⅜” size to the 7 mesh.  Back in April 2012, I was visiting with Richard Szecsy about becoming a member of the Texas Aggregate and Concrete Association.  Richard has a PHD in Civil […]

Bedding Pipe with Open Graded Crushed Limestone

Crushed limestone is used extensively for bedding underground pipe. Typically aggregate with a top size from 1 ¼” to 3/8” is used. The limestone bedding levels and supports the pipe. Pipe bedding performs for underground pipe what railroad ballast does for railroad tracks. Pipe that operates under pressure (fresh water, natural gas, or diesel fuel), […]

Crushed Limestone Concrete Aggregate

Concrete, along with steel and wood products’ are the basic building materials of our modern society. Concrete is made by mixing sand, course aggregate, water and cement. Many people confuse concrete with cement. Cement is the gray powder which forms the bonding agent when sand and course rock is mixed with water, the result is […]

Mag-Lime and Superfine Aglime

PURPOSE The purpose of this report is to give a description of the materials that Texas Crushed Stone Company produces for use as agricultural limestone. We are proud of the quality of our product and the contribution that it has made to the farmers in lime deficient areas. This report is designed to show how […]

Crushed Edwards Limestone Base

There is no better indicator of construction materials’ effectiveness and success than the materials’ service history. Crushed Edwards Limestone Base has been used extensively in the Austin Texas area since the mid 1940’s.

Determining the Need for Agricultural Limestone

The primary reason to apply agricultural lime is to correct soil acidity. Acid soils tend to occur in high rainfall areas of the world. Soils will become acid through leaching of minerals by large amounts of rainfall, removal of minerals by crops and animals harvested from the land, and the application of fertilizers. The application […]
