Pavement

• Kristin Taylor

60
Pavement Design Overview

• Soil classification within the Lake Mathews
  project area
• Flexible pavement design
• Rigid pavement design
• Final selection for pavement design

61
Soil Classification

• USDA classification of soils was found using Web
  Soil Survey v2.0.
• CBR value was found using FAA standards.
• A CBR value of four was selected.

62
Flexible Pavement Design

• Due to the gross weight of our service aircraft
  (Less than12,500 pounds) our design was based on
  light weight aircraft criteria.
• FAA specifies that no reduction in thickness
  should be made for noncritical areas of
  pavement (i.e. Apron).

63
Results of Flexible Pavement Design
References Federal Aviation Administration AC
150-5320-6D, Chapter 5 Pavements for light
aircraft.
64
Flexible Pavement Detail
65
Rigid Pavement Design

• Subbase Is required due to the soil type CH
  located within our runway.
• Subgrade 90 compaction required for soil types
  found within our project site.
• Jointing Not to exceed maximum spacing.

68
Selection of Pavement

• Flexible pavement was selected for the Lake
  Mathews Municipal Airport due to construction
  costs and timeline.

69
Grading

• Kristin Taylor

70
Grading Plan Overview

• Grading of runway and taxiway
• Grading of non-critical areas
• Final grading plan
• Earthwork

71
Runway Taxiway Specifications
72
Runway Cross Section
73
Grading of Non-Critical Areas

• Access Road 2 from the center line to the
  gutters on either side.
• Perimeter Road 2 away from runway and taxiway.
• Apron Design to allow surface flow of 1 away
  from the taxiway to the south edge of the apron
  area, where the water is treated.
• Structures For buildings and other structures a
  2 grade for a minimum of 10 feet was used.

74
Final Grading Plan
Existing and proposed surfaces showing the
grading needed for site
75
Earthwork Quantities
Summary Based on the designed grading plan a net
cut of 24,965 cubic yards will need to be removed
from the project site.
76
Airport Drainage

• Sean Hoss

77
Drainage

• Promotes safe and efficient operations
• Handles airport surface runoff
• Diverts runoff away from Lake Mathews
• Two drainage areas
• Runway handled by Volume Based drainage
• Ramp area handled by Flow Based drainage
• Based on Riverside County Flood Control District
  BMP Handbook

78
Runway Runoff

• Corrugated steel pipe
• Slope 0.005
• Di 15, Df 24
• Inlets at 400 feet or less
• Water quality inlet
• Ponding
• Rainfall gt 0.85 in/hr
• 10 acre-ft storage
• Outfall
• Extended detention basin

79
Ramp Runoff

• Filter strip (turf grass)
• 15 depth
• Wide as the ramp
• Removes pollutants and sediment
• Infiltration trench
• Aggregate 1-3
• 48 hr drawdown
• Overflow pipe to detention basin

Environmental Impact Assessment

• Denise Chow

81
Environmental Noise Impact

• Environmental Concerns
• With restrictions in time, we will concentrate on
  noise impact
• INM Integrated Noise Model
• FAA approved Airport Noise Exposure Map
• Noise contours generated with real-time values
  and coordinates
• General allowable threshold
• FAA (Advisory Circular) 65 dB
• 7 different thresholds of noise level

82
Noise Assessment Data
83
Importing Supplemental Data

• CAD graphics
• Airport runway layout
• AutoCAD DXF file for graphic enhancement
• Terrain data
• Topographic map overlay
• Signify elevation affecting noise propagation
• Street census
• Streets, highways, hydrographic features, civil
  boundaries
• Overlays street map data
• Population census
• Population points
• Enables visual inspection of sound impact on
  neighboring residents

Outcome

• Viable source for current and future noise
  predictions generated by Lake Matthews Airport
  (LMA) and its components
• Ensure LMA from causing unwanted noise around
  neighboring communities
• Homes, schools, businesses
• Easement required

90
Sound Decibel Threshold

• 65 dB Threshold
• Not designated under Federal, State, or local law
• Responsibility for permissible land use remains
  with local authorities
• Sound proofing packages
