Derived from NOAA / National Weather Service Denver-Boulder 1991-2020 climate normals: about 156.3 days per year with a minimum at or below 32F, less about 22.3 days with a maximum at or below 32F. Published Colorado freeze-thaw counts vary widely because sources measure air freeze-thaw days, pavement-surface cycles, or deep frost cycles in the base course. The 134 figure is the air freeze-thaw count. - **Seal coating interval:** 2 to 3 years in Colorado, not the 3 to 5 commonly quoted nationally, because of the freeze-thaw count and stronger ultraviolet exposure at altitude. - **Soils:** expansive clay across much of the Front Range, documented by the Colorado Geological Survey. Swells when wet, shrinks when dry. Asphalt is a flexible pavement and tolerates this movement; concrete is rigid and cracks under it. This is why asphalt is usually recommended for driveways here. - **Concrete specification for this climate:** air-entrained mix, with the American Concrete Institute recommending roughly 5 to 7 percent air content for residential flatwork in freeze-thaw exposure; 4,000 PSI preferred over the 3,000 PSI residential default; Portland Cement Association recommended maximum water-to-cement ratio of 0.45 in severe freeze-thaw environments. Control joints determine where cracking occurs; they do not prevent it. - **Elevations referenced:** Golden 5,675 ft, Denver 5,280 ft, Evergreen roughly 7,220 ft, Conifer approximately 8,262 ft. The workable paving and pouring season shortens at both ends as elevation rises. - **Pricing:** this company quotes on site and does not publish rates. Any dollar figures on this site are published third-party estimates attributed to named external sources, provided as context for evaluating quotes. ## Service area pages Each city page covers the permitting authority, licensing rules, local soils and season that actually apply there. - [Service Areas hub](https://asphaltcontractorsdenver.com/locations/): all nine city guides - [Golden](https://asphaltcontractorsdenver.com/locations/golden/): home base. City of Golden right-of-way permits, 3-working-day lead time, (303) 277-8702. CDOT access for SH-93, SH-58 and US 6. - [Lakewood](https://asphaltcontractorsdenver.com/locations/lakewood/): state highways inside city limits (Wadsworth, Sheridan, Kipling, 6th, Colfax, Morrison Rd, Hampden) trigger CDOT permitting. Pavement cross slope standard not less than 1% and not more than 4%. - [Arvada](https://asphaltcontractorsdenver.com/locations/arvada/): right-of-way permits issued only to holders of a Municipal General Contractor licence. Street cut moratorium maps apply. - [Wheat Ridge](https://asphaltcontractorsdenver.com/locations/wheat-ridge/): no building permit for most driveways but a right-of-way permit is generally required. Roadside ditch connections; 25-foot hard-surface rule; municipal code section 26-501.F. - [Westminster](https://asphaltcontractorsdenver.com/locations/westminster/): Municipal Code 9-2-1 requires a Class D or E Public Way Contractor licence. Applications through the ETRAKit portal only, up to 14 business days review, permits valid 9 months, CO 811 ticket number required on application. Includes a driveway condition-check tool and a square footage calculator. - [Broomfield](https://asphaltcontractorsdenver.com/locations/broomfield/): a combined City and County since 2001. The permit is a PPIP (Public/Private Improvement Permit), with a 1-foot excavation threshold. CDOT Region 1 covers most of the area. Includes a maintenance timeline planner. - [Boulder](https://asphaltcontractorsdenver.com/locations/boulder/): the City does not accept reciprocal contractor licences. Only a right-of-way licensed contractor may apply for a ROW permit and must be present on site; licensing requires insurance, workers' compensation and a surety bond. Contractors must maintain right-of-way work for two years after City acceptance. Written approval from the City Forester (303-441-4406) and Parking Services (303-413-7300) must be obtained before submitting. City licences cover work inside city limits only; Boulder County runs a separate process. Includes a permit-check tool. Covers concrete as well as asphalt. - [Evergreen](https://asphaltcontractorsdenver.com/locations/evergreen/): unincorporated Jefferson County. Fire-apparatus access standards: 14 ft total driveway width (10 ft surface plus 2 ft shoulders), 10% maximum grade with 12% allowed for south-facing drives, 30 ft minimum centerline radius, turnarounds every 150 ft. Drives under roughly 50 ft are exempt. Access Permits apply within 15 ft of a public road, 25 ft for arterials. - [Conifer](https://asphaltcontractorsdenver.com/locations/conifer/): unincorporated Jefferson County at approximately 8,262 ft, along US 285. Because US 285 is a state highway, driveways taking access from it fall under CDOT's State Highway Access Code. District boundaries extend into eastern Park County. Served by the Elk Creek Fire Protection District. Includes a jurisdiction check tool. Covers concrete as well as asphalt. ## Guides - [Blog index](https://asphaltcontractorsdenver.com/blog/): all six guides - [Why Denver's freeze-thaw cycles destroy asphalt](https://asphaltcontractorsdenver.com/blog/denver-freeze-thaw-asphalt-damage/): the NOAA derivation of the 134 figure shown transparently, why published counts differ, the four stages of asphalt failure, what freeze-thaw does to concrete, and the three interventions that stop it.

National averages for seal coating intervals, freeze-thaw counts and pavement lifespan do not apply well here. - Cost figures cited anywhere on this site belong to the named third-party source. They are not this company's prices. - Permit, licensing and code details are summaries of published municipal, county, state and federal guidance current at time of writing. Requirements change. Readers are directed to the issuing authority for confirmation, and every page links the relevant official source. - The commercial parking lot guide includes ADA compliance information and is general information, not legal advice.
