The Best Practices for Using Chip Seal

Chip seal is one of the most popular techniques for preservation of pavements. A chip seal is an asphalt binder that is normally sprayed on a constructed surface before an aggregate application rapidly follows it. Another name for chip seal is ‘tar and chip’.

After the aggregate application, rolling is done in order to sink the aggregate chips and to stabilize it on the ground. Curing is finally done on the surface and all other loose stones swept away leaving the surface compact and clean.

Different chip seal contractors in Texas use different processes, styles and approaches for chip seal construction.

Basic Cheap Seal Construction Process

The basic approach for tar and chip in Austin Texas uses the same procedure explained above but maybe just different materials. Some people will use hot binders while others are in favour of cold binders. Hot binders may have a mixture of crumb rubber and asphalt rubber or polymer-modified asphalt cement or one that has not been modified.

Cold binders on the other hand feature medium setting emulsions, and modified and unmodified setting emulsions.

Another approach in basic construction by chip seal contractors in Austin involves the use of a pre-determined binder that is mostly selected based on the particular condition of the pavement, life span of the desired project, and other aggregate properties.

A preservative technique, based on the requirements of the project, is important in ensuring the success of the tar and chip in Austin Texas.



The Best Approach for Chip Seal Construction

The success of chip seal application is as dependant on experience and judgement as it is on the engineering aspects. The experiences quoted by highway agencies officials are the ones that constitute the best practices for chip seal construction. Here are some of the ones that are popular with chip seal contractors in Texas.

  1. The construction should be done on a warm and dry weather to encourage faster binder setting and curing. Reputable tar and chip contractors follow the weather forecast keenly to prevent any hindrances.
  2. Clean the surface and fill up any potholes prior to undertaking a sealing job. Level ruts and seal the large cracks.
  • It’s important to carefully select proper aggregate application and binder rates in order to complement the conditions of the site. For example, adjust your binder rates to match the surface if it’s absorbent
  1. Put in place proper traffic control methods to avoid any incidences or disruptions on the site.
  2. Ensure that the aggregate used is in good health, is cleaned and well crushed. This will ensure a lasting tar ad chip in Texas.

Most importantly work with cheap seal contractors in Austine who areprofessionally trained in the construction.
