The 2026 lay season runs July 6 to September 25 — eleven weeks, because at ten thousand feet the weather permits exactly that long. Cold-patch standby runs the other forty-one weeks · (555) 051-3384 · crew@timberlineasphalt.example
What the mountain hires us for
Three trades, benched for the freeze
A valley crew can pave anything once. Paving it so the second March looks like the first is a different licence, and the three trades below are the whole of it.
Saw-and-seal jointing — $3.10 / lin ft
Thermal cracks are not a defect up here; they are a schedule. So we saw the joints first — a quarter-inch channel on layout lines the surveyor chalks, blown clean and sealed hot with the rubber recessed — and the crack that was coming anyway arrives where we put it, sealed, instead of across your drive at random. Every Timberline mat leaves here jointed.
Cold-grade binder, two lifts — $5.20–6.90 / sq ft
Valley mix is blended for valley nights; at the pass it checks like porcelain. We specify a PG 58-34 binder that stays ductile through an alpine cold snap, laid 2.5 inches in two compacted lifts over base we proof before we price, with the crown cut at two and a half percent because when the melt comes it comes as a river. The tonnage runs the same arithmetic as anywhere — eighty square feet a ton at two inches, 145 pounds a cubic foot — the difference is all in what the mat has to survive.
Switchback pads & thaw repairs — quoted on the walk
Building pads on the grade, lot rehabilitation after a hard winter, culvert-head crowns rebuilt so the ditch stops eating the shoulder, and the spring audit — every March we walk the mats we laid and cold-patch what the winter opened, free, for as long as they are ours. The audit truck is why a Timberline drive ages in decades instead of seasons.
June
Snowline check
We walk the site while the drifts still hold it. Fall, access, run-off paths and frost depth get mapped while the ground is still honest about itself.
Early July
Stakes & base proof
Hubs set to the model, base proofed and patched, geotextile laid where frost heave has worked the ground. Then we wait for the plant’s mountain window.
The window
Two lifts, hot
Binder then wearing course behind the screed at laying temperature, joints matched hot to hot, edges hand-tamped where the drum cannot reach.
Day 14
Saw & seal
The joints are sawed on their layout lines once the mat has cured enough to hold a channel, blown clean and sealed recessed.
September
The freeze check
Before the plant closes, the crew that laid it walks it once more. What goes into winter sealed goes into winter sealed.
Eleven weeks, five moves
The calendar is the spec
Asphalt at altitude is scheduling with a temperature gun. The mix leaves the plant sixty miles and four thousand vertical feet away, and every degree it loses on the climb is compaction it will never get back — so the trucks stage at the yard, the lay is sequenced to the hour, and a window that closes early is a window we do not chase. Twenty-six seasons have taught us that the mountain reads bad bids in April.

The innkeeper’s copy
The county crew paved our lot twice in nine years and it cracked both times like a dropped plate. Timberline jointed it, sealed the joints, and comes back every March to walk it before the guests arrive. Twelve winters. It is the flattest thing at this elevation and that includes the dining tables.
2025 — 2026
Laid in the window
Six surfaces from the last two eleven-week seasons, photographed before the first snow had a say. Every one is in the audit book for March.

Asked at the guard station
Why can you only lay between July and September?
Because the plant that blends the cold-grade mix only runs its mountain window then, and because asphalt needs ground temperatures the high country simply does not offer in May or October. A mat laid cold compacts to a rumor — we will cold-patch your emergency in any month, but a lay at the wrong temperature is a scheduled redo with our name on it, so we do not sell it.
A valley crew quoted me a dollar-fifty less per foot. Why?
Because their binder is blended for their nights, their mobilization is one switchback instead of seven, and their calendar is twelve months long. What that bid does not carry is the PG 58-34 upgrade, the saw-and-seal pass or the March audit — and by the third spring it is not cheaper, it is arithmetic you get to do twice. Sometimes the valley crew is the honest answer at the lower cabins; the walk decides, and we say so there.
What happens when a crack appears anyway?
It appears in a sealed joint, which is where it was invited to appear — that is the whole point of saw-and-seal. If a crack crosses the field of the mat inside the joint warranty, the routing and sealing is on us, and the March audit would have found it before you did. A mat that cracks outside its joints up here almost always means water got under it, and the audit book tells us whose fix that is. It has been ours twice.
Do you plow or maintain lots through the winter?
Cold-patch standby and the spring audit, not plowing — a plow blade on a jointed mat is a chisel looking for a seam, and we would rather the audit truck was the harshest thing that visits. Member lots get first call on the standby trucks all winter, and everyone we have ever paved for gets the March walk, free, for as long as the mat is ours.
Our switchback pad had been quoted three times by valley crews who all wanted it in June, when it is still a bog. Timberline walked it in snowshoes, laid it in the last week of July, and jointed it so the crack field reads like graph paper. Four winters, not one unplanned seam.
The March audit is the part nobody believes until the truck shows up. They walk the whole lot with a kettle of cold patch and a ledger, fix what the winter opened, and leave the page for the file. Our maintenance line for asphalt has been zero for six years.
They told us to wait a season for the plant window instead of taking our money in May, and they were the only bid that mentioned binder grade at all. The drive they laid the last week of the window has outlasted the two valley-mix mats beside it by five years and counting.
The snowline walk is free
Send the parcel and what the ground does. We walk it while the drifts still hold it, the July number goes on paper before the plant opens, and the March audit starts the day the mat cools. crew@timberlineasphalt.example
