Concrete curb, gutter, or paved concrete shoulders may separate from or settle along the main pavement. The longitudinal joints between the pavement and curb or shoulder may open, fault, or deteriorate like other longitudinal joints. Concrete Welder can be used to seal and repair the joints before the damage is too bad. When severe enough [...]

Pavement Damage 16, Utility repairs– patches and potholes
Replacement or repair of utilities will require cuts or utility openings. When repaired these pavement patches may show settlement, joint deterioration, or distress under continued traffic loading. Patches from previous repairs may perform like original pavement or experience joint deterioration or settlement. Localized failures of materials or subgrade soil can cause individual potholes. Surface spalling [...]
Pavement Damage 15,Pavement Settling or Heaves
Unstable or poorly-drained subgrade soils may cause pavements to settle after construction. Poorly-compacted utility trenches may also settle. This may be a gentle swale or a fairly severe dip. Frost-susceptible soils and high water tables can cause pavements to heave during the winter months. Water will freeze, expand and cause cracks. Extensive pavement cracking and [...]
Break From Concrete Damage
I was thinking about how many blogs we have about conrete damage types and how many there are still. When I’m done with the Paser Ratings Concrete Damage descriptions, I plan to write about asphalt damage. Although there are fewer types of asphalt damage, it still felt like time for a break. So, for a [...]
Pavement Damage 14, Faulting in Concrete
Joints and cracks may fault or develop a step between adjacent slabs. Faulting is caused by pumping of subgrade soils and creation of voids. Heavy truck or bus traffic can rapidly accelerate faulting. Longitudinal joints may fault due to settlement of an adjacent slab. Faulting creates a poor ride and may cause slab deterioration. Minor [...]
Pavement Damage 13, Blowups
Concrete slabs may push up or be crushed at a transverse joint. This is caused by expansion of the concrete that has caused breakdown and incompressible materials (sand, etc.) have infiltrated into poorly sealed joints. As a result, there is no space to accommodate expansion. It is more common in older pavements with long joint spacing. [...]
Pavement Damage 11
Concrete Damage Series, Part 11 Corner cracks Diagonal cracks near the corner of a concrete slab may develop, forming a triangle with a longitudinal and transverse joint. Usually these cracks are within one foot of the corner of the slab. They are caused by insufficient soil support or concentrated stress due to temperature-related slab movement. [...]
Types of Pavement Damage 10
Concrete Damage Series, part 10 D-cracks Occasionally, severe deterioration may develop from poor quality aggregate.D-cracking develops when the aggregate is able to absorb moisture. This causes the aggregate to break apart under freeze-thaw cycles which leads to deterioration. Usually, it starts at the bottom of the slab and moves upward. Fine cracking and a dark [...]
Types of Pavement Damage, 9
Concrete Damage Series, Part 9 Transverse Cracking Transverse cracks may appear parallel to joints and can be caused by thermal stresses, poor subgrade support, or heavy loads. Transverse cracking is sometimes related to slabs having joints spaced too widely. Joints spaced more than 15’ apart commonly develop mid-slab transverse cracks. As with joints, these cracks [...]
Types of Pavement Damage 8
Concrete Damage Series, Part 8 Transverse Joints Transverse joints are constructed in concrete pavements to permit movement of the concrete slabs. Some joints are constructed with load transfer dowels. If the pavement has poor subsurface drainage, traffic may eventually create voids under the joints due to friction and cause the slabs to settle or fault. [...]
