This year’s Microsurfacing pavement preservation road preparation begins on Wednesday, August 7 in Central Richland. Residents will be given notices by the contractor, Intermountain Slurry Seal, Inc. prior to work being done on their street. Additionally, no parking signs will be in place a few days before, warning about parking on the streets. 

Microsurfacing is a mixture of fine aggregate, emulsified asphalt, and chemical additives that is applied to City roads. This preventive maintenance extends the life of existing asphalt while sealing it from the harmful effects of water penetration and sun.

During street preparation, commuters can expect temporary or partial traffic impacts before the sealant application closes down the road for part of a day. When applied, the material is brown and sticky. Cars, bicycles, people and pets must be kept off the surface until it is cured and the street has reopened. After a couple of weeks of cure time, crews will return to apply permanent striping.
