The City of Marshalltown, in partnership with its contractor Corrective Asphalt Materials, will conduct a pilot test of a specialized asphalt rejuvenator product, CRF®, beginning Nov. 4-10, weather permitting.
While the City successfully rehabilitated over 70 blocks of asphalt through mill-and-overlay projects this year, Public Works recognizes that many streets still require maintenance, rehabilitation and reconstruction. This pilot project tests a cost-effective, preventive preservation method designed to slow asphalt deterioration and extend the lifespan of municipal roads in future street improvement programs.
Testing will take place on four targeted street segments representing varying levels of road deterioration:
North Ninth Street (West Church Street to West State Street)
West South Street (South Sixth Street to Center Street)
East South Street (Center Street to South Third Avenue)
South Third Avenue (East South Street to East Anson Street)
To minimize overall disruption, work will proceed one lane at a time. The City asks drivers and residents to note the following operational impacts:
• Single-Lane Closures: Flaggers will maintain alternating single-lane traffic through active work zones.
• Parking Restrictions: On-street parking is strictly prohibited during treatment and street-sweeping operations. Look for temporary posted signage.
• Temporary Driveway Delays: Residents may experience brief periods (approx. 45 minutes) of restricted driveway access while the liquid emulsion penetrates the road surface.
• Tracking Prevention: A thin layer of sand will be spread over the treatment after initial penetration to reduce sticking, spraying and off-site tracking of residual treatment emulsion. Traffic will resume once sand is applied. The sand will remain on the street for approximately five days before street sweepers collect and remove it.
City officials ask motorists, bicyclists and pedestrians to exercise extra caution in work zones, observe parking restrictions, obey flagger directions and avoid driving through freshly treated areas until sand is spread to prevent tracking the emulsion onto personal property.
“We appreciate the patience and cooperation of our residents and visitors as we explore new solutions to slow the deterioration and extend the life of Marshalltown’s roadways,” said Marshalltown Public Works.
