Cement Standards and Concrete Standards. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
Pavement Repair Guidelines for Longitudinal Joints 1.1 Problem description As concrete highways of Texas age beyond their original design/service life expectations, one type of distress has become more common on Texas highways — longitudinal separation and faulting. This distress leads to uneven roadway surfaces;

Concrete Repair Guidelines Concrete repairs can be broken down into four basic types, plus special repairs and diamond grinding. Note: It is recommended that an investigation into the soundness of pavement be performed before identifying a project for specific repairs. This investigation should include 'chaining' the pavement,
A second crew will re-grade the area and place the form boards for the new concrete. This may include trimming the tree roots as needed. A third crew will pour and finish the new concrete. Once this task is complete, it may take up to 7 days for the concrete to cure or get hard enough to drive across it.
Following these guidelines doesn't necessarily assure a successful and durable repair but it does provide a system for making decisions based on the many years of experience from the authors.

For ADA compliance, the minimum sidewalk width is 36 inches (3 feet), though sidewalks can be wider. If sidewalks are less than 60 inches (5 feet) wide, passing spaces must be constructed every 200 feet. These passing spaces (which could be a driveway or wider section of concrete) need to be at least 60 inches on all sides.
