Micro-surfacing is a low-cost asphalt emulsion application process that utilizes specialized equipment to combine polymer, mineral aggregate, water, and additives. Once the mixture cures by water loss, it bonds with the existing pavement creating an extremely durable surface that can last for several years. It adheres firmly on the prepared surfaces with skid-resistant textures throughout its service life.
Microsurfacing performed by an experienced, professional asphalt contractor like National Pavement Partners in Denver, Colorado Springs, Fort Collins, Loveland, and Castle Rock, CO, lasts a long time.
This blog post shares nine essential micro-surfacing guidelines to ensure the process produces the desired results.
- During a mix design, you should assess the aggregate, emulsified asphalt, water, mineral filler, and other additives’ compatibility to ensure the project’s success.
- All material components – aggregate, asphalt emulsion, water, and additives – must individually be tested and satisfy the work requirements and testing standards.
- To make sure that micro-surfacing is applied correctly, a contractor needs to be aware of temperature and humidity levels and wind conditions. All three impact the amount of time required for water additives and field materials used during construction.
- Before loading the mobile support unit, screen the material that will be used. This way, you can prevent any contamination when re-handling it.
- When filling ruts or low spots, it is impractical to measure the material needed. So do not specify an application rate for a leveling course when laying one down, as you may not know how much material would be required.
- Inspections are integral to ensuring that a job is done correctly. When the materials change, conveyor seals and emulsion pumps have been replaced, ask for a recalibration by the contractor on-site to increase quality control within their workmanship.
- When applying the crack sealing material, ensure that it is not too thick. If this happens, micro surfacing paver tires and spreader box runners can pick up some of the excess sealants and carry it onto other areas intended to be left clean.
- To extend the life of a micro-surface application, only apply it to parking lots and other pavements that won’t receive heavy traffic.
- You should use a laboratory accredited by the American Association of State Highway and Transportation Officials (AASHTO) or its equivalent when conducting tests.
