Concrete Parking Lots : 

Concrete Parking Lots By: Dennis Murray, E.I

Concrete Parking Lot : 

Concrete Parking Lot The Purpose is to help designers recognize the best available choice when it comes to parking lot paving.

Concrete Parking Lot : 

Concrete Parking Lot Goals To dispell the high cost of using CONCRETE To show CONCRETE is a smart choice To prove that’s it is easy to design w/ CONCRETE

CoMPETITIVE INITIAL COST : 

CoMPETITIVE INITIAL COST

Competitive Initial Cost : 

Competitive Initial Cost Here are the misconceptions: CONCRETE is better so it must cost more CONCRETE pavement has to be 6” or greater Soil compaction has to be 98% modified proctor Pavement cross-slope has to be 2% minimum Asphalt will always be cheaper!

Competitive Initial Cost : 

Competitive Initial Cost Here are the facts: CONCRETE is BETTER, but does not have to cost more. Use ACI 330 for 20-yr thickness design Compact subgrade soils to 95% standard proctor Min. 1% slope, potentially less drainage structures Cheaper asphalt – “You’ll get what you’ve paid for” Volatility of the petroleum industry Improved processing techniques (20% - 7%/ Barrel) Construction meets design??? (Inspection & Testing!)

Volatility vs. Stability :

Structural Comparison : 

Structural Comparison 2.49 2.16 Structural No. 13.25% Service Life

Competitive Initial Cost : 

Competitive Initial Cost First Court of Appeal – 8% Less with CONCRETE! Specified Asphalt: 1.25” Asphalt Type SP-12.5 0.75” Asphalt Type SP-9.5 8” Limerock Base 12” Stabilized Subgrade (98% modified proctor) $24/SY in-place Recommended Concrete: 5” with 4000 psi Uniform support Type of Soils Moisture Content Density (95% standard) $22/SY in-place 13,000 SY of Paving (185+ Parking Spaces) – March 2009

CoNCRETE IS A SMART CHOICE : 

CoNCRETE IS A SMART CHOICE

Concrete is a Smart Choice : 

Concrete is a Smart Choice Here are the misconceptions: Paving equates to Asphalt Save my clients money Asphalt lasts as long as CONCRETE Asphalt is environmentally friendly

Concrete is a Smart Choice : 

Concrete is a Smart Choice Here are the facts: Doing the same ≠ Ingenuity Prior to 2006, but long-term CONCRETE is Less Design Life: CONCRETE – 20+ vs. Asphalt – 7-12 yrs Asphalt is… a petroleum product not a product a product that absorbs heat a product that gets sealcoat regularly (every 3 to 4 years!!) a low reflective product, thus needs more lighting a “perpetual” product that needs more maintenance after warranty had expired green

Concrete is a Smart Choice : 

Concrete is a Smart Choice

Slide 14: 

Asphalt Parking Lots use 57% more electrical energy than concrete, on average. Based on PCA’s Influence of Pavement Reflectance on Lighting for Parking Lots Concrete is a Smart Choice

Ease of design w/ concrete : 

Ease of design w/ concrete

Ease of Design w/ Concrete : 

Ease of Design w/ Concrete Here are the misconceptions: Don’t know where to start What references should be used What thickness is appropriate How to layout proper contraction joints What details are available

Ease of Design w/ Concrete : 

Ease of Design w/ Concrete Here are the facts: FC&PA’s Engineers or Regional Supports ACI 330 (Parking Lot) & ACI 522 (Pervious Concrete) For thickness: (ACI 330 20-YR Design Table) Light Wt – 4.5” Heavy Wt – 6” FC&PA Standard Details which can be downloaded from www.ConcreteParkingLots.com.

Ease of Design w/ Concrete : 

Ease of Design w/ Concrete Here are the steps: Determine concrete compressive strength (e.g. 4000 psi) Determine k-value of soils Select traffic category Determine quantity of heaviest traffic load Result is recommended by 20-yr thickness table

Consequences & next steps : 

Consequences & next steps

Consequences : 

Consequences Continue Business as Usual Not providing the best solution Not in tune with environmental issues Not maintaining competitive edge Provide Cost-Effective Choices/ Options Show Added Benefits of CONCRETE Win Contracts for Ingenuity

Next Steps : 

Next Steps Provide values in your service by incorporating cost-savings options: CONCRETE Parking Lot! CONCRETE’s a smart choice, financially & environmentally 3 Association engineers, standard details, local & national references, and joint layout assistance: It’s easy to design w/ CONCRETE.
