Important Tips for Smaller Asphalt Jobs
Carparks, Driveways, Footpaths
Too many times a cheap job is done, and the result is a poor finish and a pavement that will not last as long as intended.
The paving contactor must plan the work carefully so that it can be carried out in the fastest possible time to maintain asphalt temperature. They must have skilled workers, correct and sufficient paving and compaction equipment on site – particularly the correct rollers.
Key questions to ask when choosing an asphalt paving contractor:
- Is there a specification or standard that forms the basis of their work? At least AS3727.1 – Residential Pavements – should be used. For larger jobs – say greater than 2,000m2 then use AS2150 – Asphalt – Guide to good practice.
- Will the base be prepared or constructed to the best standard for the asphalt’s intended use? Is it properly compacted and built to the correct levels?
- Has the draining of the pavement and surrounding areas been considered and designed to stop water ponding or getting into or under the asphalt?
- Does the asphalt producer/supplier test their products to a level that will provide assurance of compliance and quality? Do they have an accredited Quality Assurance System in place- e.g., AS/ISO 9001? (Not essential but good to have).
- Does the asphalt contractor have the experience and a reputation for good workmanship. It’s a good idea to ask if you can look at some of their previous work. Do they have an accredited Quality Management System in place- e.g., AS/ISO 9001? (Not essential but good to have).
- Will the contractor assess the prevailing weather conditions to determine if the paving can proceed or whether it should be delayed until there are better conditions?
- Is there a warranty or defects liability clause in the contract and does the contractor provide a completed pavement care and maintenance guide?
