Next Generation of Pavements Compacted Concrete Pavement (CCP) Burbank-Second Avenue (Walla Walla County) June 2017 Wm Winkler Company constructed the next generation of rigid pavement known as Compacted Concrete Pavement (CCP) at the Port of Walla Walla-Burbank Industrial Site for Walla Walla County, Washington. This is the first CCP project constructed in the northwest United States. CCP utilizes similar technology to Roller Compacted Pavements (RCC) with additional additives and finishing processes to enhance the durability and ride-ability of the pavement. The mix includes ACEiT Plus Additive to stabilize the moisture, reduce the viscosity and inhibit the hydration process until it is mechanically activated. During finishing ACEiT Blue Finishing Agent is topically applied and power troweled to increase surface durability and abrasion resistance while reducing permeability. The product increases freeze thaw durability while allowing traditional finishing techniques that are indistinguishable from conventional concrete. The placement achieved exceptional density and strength with 97% compaction immediately behind the paver and 5000 psi strength in the first 24 hours. The product was manufactured on-site with a portable batch plant and placed with a high density paver. The 5,000 Square yard Second Avenue accommodates heavy truck access to the Port of Walla Walla in Burbank, WA. This new generation will provide pavements that will withstand freeze thaw cycles, avoid the pot-holes that plague communities throughout the region while offering cost competitive initial construction costs. Life cycles for the CCP will extend beyond 40 years with minimal maintenance. For more information contact Pete Reed at 509-489-6100 ...

Emergency Slide Repair-Matsen Creek US 395 (2017) (WSDOT/Eastern Region) Wm Winkler Company in conjunction with WSDOT/Eastern Region and Colville Maintenance successfully opened US HWY 395 at Matsen Creek in just 30 working days after a major landslide. The project encompassed erosion control, geotechnical analysis, waste and tree removal, over 39,000 tons of imported structural fill, 12-foot diameter corrugated metal pipe, seeding, asphalt reconstruction, pavement marking and guardrail. “Quite a feat and accomplishment in 30 days! This is something to be proud of!” Tom Brasch, PE Project Engineer, WSDOT/Eastern Region Landslide Reconstruction ...

We're proud to announce that Wm. Winkler Company has received awards from the Washington Aggregates & Concrete Association for our work on US 195 and the Monroe St. Lincoln St. couplet.   ...

Wm. Winkler Company was presented with two awards at the 2017 Inland Northwest AGC Convention for Technology in Construction. Special Projects: Riverfalls Tower Deck Reconstruction Project Description: The Riverfalls Tower Structure is a 15 story facility including 4 lower levels of parking garage and 11 stories of condominiums.  The concrete cast in place structure was originally constructed in 1972.  Level 5, where the reconstruction occurred, is the main on-street level incorporating a porte-cochere lobby entrance, street level exterior parking, access to the lower parking garage as well as delivery of services, ADA and other vehicle and pedestrians. The area reconstructed is a 44 year old cast in place concrete deck (with parking structures beneath) capped with thin-set brick pavers.  Two significant water features were incorporated on this deck at the main entry.  Water migration through the deck and the water features had seriously deteriorated both the use and the structural integrity of this concrete deck.  The deck underside, a roof in the lower parking garage, was experiencing concrete failure and reinforcing corrosion.  A structural overlay was not possible due to the restricted clearance of the existing porte-cochere as well as additional weight impacting the CIP structure.   Sub-Contractor: Monroe Street/Lincoln Street Couplet - City of Spokane Project Description: This project encompassed a total reconstruction of the Monroe/Lincoln Street corridor. The concrete work included 2,380 CY of PCC pavement, curb and gutter, sidewalks, driveway transitions, traffic curb and island in-fills and one retaining pond.  Limited access and steep grades impacted construction with an extremely short schedule. With grades exceeding 13% and a narrow corridor, the precision to establish and maintain a multitude of break points both longitudinal and transversely created many challenges.  Access for pump and ready mix trucks on the incline had to be carefully calculated to allow maximum reach while maintaining allowable slumps and final elevations during the pour and final finishing.  With an accelerated PCC Pavement schedule, it was essential to maximize the length of pours without latitude for multiple access points.  New intersection from cross streets required careful layout and forming to insure ADA compliance at the ADA ramps while also pouring steep grades on the main roadway.  With a sustainable contrete pavement the City will enjoy decades of performance with minimal maintenance....
