Chapter 12 – Right of Way Permitting and Construction Standards for Facilities Located in Public Right of WaySection 12.3 Construction Detailsb. EXCEPTIONS - There may be situations where the patching standards areconsidered inappropriate. For example, rebuilding half of a road today whenthe road is due for reconstruction at a different profile in 2-3 years wouldconstitute the Engineer modifying the patching requirements. In these cases,the Permit Holder may be allowed to provide a more modest patch adequateto accommodate traffic for the 2-3 year period. In return, the Permit Holdermay be required to make a financial contribution to the road maintenance,rehabilitation or reconstruction program to support the more permanentimprovements that are anticipated. This determination shall be made by theEngineer.c. DISPUTE RESOLUTION - Mutual acceptance of these standards is expectedto evolve over time with experience in the field. Disagreements overrequirements and cost sharing are inevitable. In cases where agreementcannot be reached, the dispute shall not relieve the Contractor fromcompliance to the specific Permit or standards provided by this documentunless approved by the Engineer.12.3.8.4 Concrete Surfacing and Patchinga. Concrete pavement shall be replaced with 4,000 psi concrete to match thefinish and thickness of the existing pavement, but not less than eight (8)inches thick. All concrete construction shall be protected from vehiculartraffic, including contractor vehicles, until the concrete has achieved eighty(80) percent of its ultimate strength. Concrete shall be coated and sealedwith a uniform application of membrane curing compound applied inaccordance with manufacturer’s recommendations.b. The use of quick curing concrete (3000 psi strength within 48 hours) shall beused on all arterial and collector roads when repair areas are less than 500square feet or when temperatures are below 40° F. Quick curing concreterepairs may be opened to traffic within two (2) days or when the concrete hasachieved eighty (80) percent of its design strength.c. Where existing cracks or damage is adjacent to the area being repaired, therepair area shall include the cracked or damaged concrete. Pavementrepairs shall include all areas of damage, including leak test holes, pot holes,equipment and/or material scaring of the exiting surface.d. When repairing concrete, the removal perimeter shall be saw-cut anddoweled prior to placement of new concrete as directed by the Engineer.12.3.8.5 Joint Fillinga. Asphalt. Following placement of the asphalt surface, the joints where thenew asphalt abuts the old shall be sealed with a fog or painted coat ofbitumen cement.b. Concrete. Joints shall be thoroughly cleaned of all foreign material then filledwith a hot-poured elastic type joint filler conforming to M 173, ASTM D1190-80 or ASTM D1751-83, D1752-84, D3405-78, D3406-78, D3407-78 orsilicone sealants or others as approved by the Engineer. Joint material shallbe filled to within 1/2 inch of the surface. Excess material shall be scraped offto provide a smooth riding surface.Larimer County Rural Area Road Standards Page 12-11October 22, 2007
Chapter 12 – Right of Way Permitting and Construction Standards for Facilities Located in Public Right of WaySection 12.4 Developing a “Quality” Approach to Road Repairs12.4 DEVELOPING A “QUALITY” APPROACH TO <strong>ROAD</strong> REPAIRS12.4.1 GeneralEvery road and road repair situation is unique. Design criteria and constructionstandards cannot address every situation but, in order to maintain some form ofconsistency, these standards have been developed. In most cases, they provide theminimum acceptable standards for construction or repair. Consequently, when strictlyapplied, they will provide the minimum acceptable product. Therefore, this criteria hasbeen developed to maintain the same integrity of the road pavement and subsurfacecondition prior to its being cut for utility installations.To achieve the goal of “Quality” or “Excellence” in road repairs, these criteria shall beviewed as minimum standards when used in conjunction with good planning andjudgment. This will restore the road to an acceptable condition with minimal patchingfailures. In most cases, it will be necessary to exceed the minimum standards toachieve a quality repair.Issues that shall be considered in a quality approach to road repairs are as follows:12.4.2 AppearanceDoes the final appearance of the road suggest the repairs were planned, or that theyhappened by accident?1. Consciously or not, the driving public “rates” the appearance of the road system,including road repairs, every day. Road repairs which are not done satisfactorilyfrom a functional point of view may produce a negative reaction from the public ifthey give the appearance of being poorly planned or executed.2. The public’s perception of road repairs is based primarily on shape, size, andorientation -- the geometry of a patch. The following shall be consideredminimum standards for the geometry of a quality patch:a. Existing pavements should be removed to clean, straight lines parallel andperpendicular to the flow of traffic. Do not construct patches with angledsides and irregular shapes.NOT ACCEPTABLEACCEPTABLELarimer County Rural Area Road Standards Page 12-12October 22, 2007
